alright, need some help with this problem, not sure if im right or not:

Evaluate the integral:

∫[(7π)/(6),(11π)/(6),4cscθcotθ,θ]

calculating this, i got 0 as my answer... is that correct?

$$\frac{\mathbb{d}}{\mathbb{d}x} \csc x = -\csc x \cot x \iff \int \csc x \cot x\ \mathbb{d}x = -\csc x \ +k$$
